Which of you as I, miss a clean solution to manage his todos with the N900?

At the moment there is unfortunately still no iSync plugin
#NokiaFail

Therefore, I am looking for another solution to solve the issue to manage my todos from N900 to my Mac.

Has anyone of you manage this or workaround for this to mange his todos?

Preference would be of course a possibility of synchronization with the Macintosh or a webbased solution.

Thx,
pitmac
